Glocks newest pistol is not the single stack versions of the standard double stack Glocks. It is the double stack version of Glocks only single stack pistol. When a lot of Glock owners have been hoping for single stack Glocks, Glock did the exact opposite. So if everyone was wanting a Glock "rifle" would that inspire Glock to make a carbine? While I like the idea of the 30s because it is an new idea kinda. It would be nice to see something that really is new from Glock.
